PRINTING-TELEGRAPH.

Specification of Letters Patent.

Patented May 25, 1909.

Application filed August 25, 1908. Serial No. 450,127.

To all whom it may concern:

Be it known that I, lsinon Krrsnn, a citizen of the United States, residing in the city of Philadelphia, coun" y of Philadelphia, and State of Pennsylvania, have invented a new and useful Printing-Telegraph, of which the following is a specification.

My invention relates to printing telcgraphy and more particularly to printing telegraphy when practiced over a long land line, a submarine or other cable, or in any relation where the impulses arriving at a receiving station are feeble.

My invention resides in a printing telegraph in which synchronism between the transmitting and receiving apparatus is not necessary, the receiving apparatus being controlled by a line or cable relay responsive to feebly received impulses, such relay controlling master step by step mechanisms each of which is capable of controlling a plurality of printing circuits, eachmastcr also controlling a plurality of associate step by ste mecham isms, each of which controls a pliu'ality of printing circuits.

The transmitting apparatus may be a simple hand-operated key, a tape transmitter, or any other suitable type of transmitter which will impress upon the line or cable electrical impulses of relatively short duration and which succeedeach other at, relatively short and preferably equal intervals, such impulses being all positive, all negative, or part. positive and part negative. The initial positive impulse or impulses impressed upon the line or cable control one master stop by step mechanism, while the initial negative line impulse or impulses control another master step by step mechanism, and these master mechanisms each control a plurality of associate step by step mechanisms each of which controls one or more printing circuits.

For an illustration of one of the forms my invention may take, referiuice is to be had to the accompanying drawing, which is a diegrammatic view of the circuits and apparatus of the receiving printing apparatus.

L represents a telegraphic line or cable in which at a receiving station is connected the winding of a polarizedrelaylt whose tongue or armature is norn'tally at rest midway between the two contacts 1 and 2, under the influence of thdspring At the transmitting station therefore impressed upon the line or cable L a -plurality of relatively short impulses, either positive or negative,

succeed each other at relatively short intervals. If, at the transmitting station a short positive impulse be impressed upon the line, the relay tongue t will momentarily engage the contact 1 and then return to normal position. T hisshort contact, however, sufiices to allow current to llowl'rom the battery at through the winding of the sluggish relay magnet 5 through the tongue t, contact .1, conductor 6, thence through the winding of the electro-magnet 7, conductor 8 to the contact I) of the master step by step mechanism B, thence through the brush 9, which is mechanically and electrically connected with the notched metallic wheel 10, thence tl'irough the brush 11, which is always in electrical communication with the Wheel l0, thence by comluctor 12 to the other pole of the battery 4. In consequence, the quickly acting clcctro-mtignet 7 is energized and attracts its armature carried by the pivoted lever 13 to which is .pivoted a second lever 14 which engages the teeth upon the notchcdplate 15 of the master step by step 3 mechanism A. In. consequence, the notched wheel 15 is stepped around in a clockwise direction, an angular distance corresponding with the angular width ol' a tooth, and is there locked, the brush 16, carried by wheel 035 15, being then moved oil' of ci'nitact (L on to contact of. It, now, no other hne impulse,

either positive or negative, is transmitted the brush 16 remains upolr'colltact u/ and the n'inting magnet 17 is momentarily energized )ccause the sluggish magnet 5 has attracted its armature lever in to break circuit at contact 19, thus allowing l'ull current. from battery 20 to flow through conductor 21, condin-tor 22, winding of the magnet- ].7, contact o, brush 16, wheel 15, conductor 23, thence through the three pairs oi contacts 24, 26. 27; and 28, 29, associated respcctively with the notched wheels 30, 31 and 32 of the controlled associate step by step mechanism A, A and A. When. these wheels are in normal position these 1pairs of contacts are in engagement with-cue 1 other, as shown, thus rendering the conductor 23 continuous. The current passes on then through conductor 33, conductor 34, thence through conductor 35 to the other pole of the battery 20. The printing magnet 17 being thus en rgized prints :1 character in the well known manner.

Between the conductor 35 and one pole of which pthe battery 20 is connected the winding 36 of "a sluggish magnet which is also energized when the printing magnet 17 is energized, but operates somewhat more slowly and cx'cn "ally causes the armature lever or --i-, tong'u 3T loengage contact 38 thus closing a circuit through the battery istijwnductor 40 and all of the magnets 41,42,43,41tinserics with each other thence through conductm' 4-3, and all the magnets 4o, 47, lb and 4!),all

to in series with each other, thence through conductor St] to the tongue or armature 37, thus causingall these magnets to be simultaneously energized, lfia'ch, accordingly, a ttracts its dog 51. but since all the step by I step mechanisms, e.\ copt- A, are in normal position, there isno ei'l'ect ekcept in the case of magnet 49 which, when it attracts its dog 51., releases the notched wheel of the. master mechanism l .,,which'then returns to normal position under the influence of the spring 5'2, the pin 53, carried by wheel 1:), coming against the brush 54, which is always in contact with the wheel 1:"), thus bringing the wheel 15 to a restat normal position.

Similarly, if only a short negative impulse be impressed upon the. line or cable 'l, at the transmitter, the tongue t of the relay'lt momentarily engages contact 2, whereupon current flows from the battery 4, through so the winding of the magnet tongue t, con

tact 2, conductor 55, winding of electrp- 'magnet .36, conductor 57 through contact a of master A, brush 16, wheel 15, brush 54, conductor 58 to the other ole of the battery 4, thus energizing the quickly acting magnet 56 causing it to attract the pivoted lcver59 and actuate the lever 60, pivoted thereto, to

,--step the wheel 10 around one notch, thus -moving the brush 9 away from contact I) on to contact I). Simultaneously, the sluggish magnet 5 has been momentarily energized and breaks circuit at contact 19 causing current to flow from battery 20 through conductor 21-, conductor 61, through the wind-' 4 5 ing of the printing magnet to the contact 6, brush 9, wheel 10, conductor 63, thence through the pairs of closed contacts 64, 65; 66, 67; and 68, 69 associated respectively with the controlled associate step by ste mechanisms B, and B, thence through conductor 70, conductor 71, thence through conductor 35 to the other pole of the battery 20 through the winding of the magnet. 36

thus energizing the printing mag-net .62 to print a character, as well understood in the art. Simult-ancously, however, the magnet t i 36' is momcntarily energized and eventually l closes circuit at contact 38 to'again energize all ot'thc release magncts4l to 4.4 inclusive 1:0 and at; to 4 inclusive which will then cause i the wheel it) of master It to return to normal position under the inllucncc of the a )ring 72, l the pin 73 coming into contact with )rush ll, to sto wheel it) in normal position. Sup- 5 c5 pose, however, that a positive line impulse is l immediately succeeded by a negative impulse. The relay tongue t first engages contact but for an instant only, nasmuch as the succeeding negative impulse quickly' the winding of the magnet 5, tongue t, con tact '2, conductor 55, winding of the electromagnet 74, conductor 75, contact a), of master A, brush 16, wheel 15, brush 54, conth ctor 5;. to the other pole of the battery 4, thus energizing the quickly acting magnet 74 and. causing it to step the wheel 32 around until the brush 7 6, carried thereby and in electrical connnunicatioii therewith, engages contact 77; whercupoii printing magnet 7-8 is energized by current from battery- .20, the

, magnet. 5 being so sluggish that the circuit at it) is not interrupted because of the extremely short contact between t and contact 1 due to the positive impulse inuncdiately followed by a negative impulse. Then immediately after the printing magnet 78 has been energized and a character printed the sluggish magnet 236 has again responded to energize all of the releasing magnets, whereupon wheel 15 of master A and wheel 32 of the mechanism A are restored to normal by their res ective-springs. The stepping ol the whee 32,-however, has allowed contact 29 to separate from contact 2h thus breaking the circuit including the conductors 23 and 32. Upon restoration to normal, however, the pin, carried by the wheel 32, has again closed circuit at 28 and 29.

It is to be noted also that the movement. of thebrush 16, of master A, to contact a" has prevented current from passing through the n'ragnet 56, of the master 'B, because the I circuit is open at contact a of master A; Similarly, if two positive line impulses are succeeded by a negative line impulse, the brush 16, of master A, is quickly stepped around into enga ement with contact a and then the contact between t and 2 allows current to pass from battery 4 through con-- ductor 55, through the winding of the magnet 79 of the step mechanism A, thence through conductor 80 to contact a of master A,-

around into engagement with contact a in which case the succeeding negative impulse causes current to pass through the winding of the operating magnet 83 of the step mechanism A until its brush 84 engages contact 85 allowing current to pass through the winding of the printing magnet 86. Or, if, in any of the last three cases described, more than one negative impulse succeed the initial positive impulse or impulses the brush 76, or the brush S0, or the brush S4 is stepped around a corresponding number of spaces to engage a corresponding contact and thereby close the circuit through a corresponding printing magnet.

If the received impulses be one negative followed by one or more positive impulses'the master B controls the step mechanism B- having actuating magnet 130, wheel 87 and brush 88 to step around a number of spaces corresponding with the number of received positive impulses to engage one of the five associated contacts to control one or the other of the five associated printing magnets in the group 89, 90, 91, 92 or 93. Or, if two initial negative impulses be followed by one or more ositive impulses, then the step mechanism 2 having actuating magnet 129, wheel 94 and brush 95 is stopped around to close the circuit of one of the printing magnets 96, 97, 08, 99 or 100, depending upon the number of positive impulses. larly, if three initial negative impulses be succeeded by one or more positive impulses, then the master 13 controls the step mechanism B having actuating magnet 12S, wheel 101 and brush 102, to step that brush around a number of spaces corresponding with a number of positive impulses to close the circuit of one of the printing magnets 103, 104, 105, 106, 107 or 108. If either more than three positive or more than three negative initial impulses are received the associated step mechanisms A, A and A, B, B and B are not actuated but, in the case of more than three positive impulses, either contact a or contact a, of master A, is engaged by brush 16, and either one or the other of printing maguets109 110 is energized or in the case of more than three negative impulses the brush 9, of master B, engages either contact I) or If to energize either printing magnet 111 or printing magnet 112.

In the case of step mechanism A, if, three initial positive impulses are succeeded by more than one negative impulse, the brush 84 is stepped around a number of spaces corres )onding with thenumber of negative inipul scs, so that one of the printing magnets 113, 114 or 115 is energized; and, similarly, in the case of ste mechanism A, if the two initial positive impulses be succeeded by more than one negative impulse, the brush 80 is stepped around a number of spaces corresponding with the number of negative 'ters, and five And, simitwo master step mechanisms, one responsive to positive impulses and the other to negative impulses, and with three associated step mechanisms controlled by each master, each associate mechanism controlling five printin circuits, it is possible to print forty (40) di ereiit characters, five by each of the masby each of the associate step mechanisms. The master A, in addition to the printing magnets 17, 109 and 1100011- trols printing magnets 124 and 125 controlled respectively by contacts a' and a; and in master B the printing magnets 126 and 127 are controlled respectively by contacts I) and b What I claim is:
